Specification of Letters Patent.

Patented June 9, 1914 application filed November 25, 1912. Serial No. $133,323.

To till whom it may concern:

Be it known that T, TnoMAs CHRISTIAN Annnnsmv, of Viborg, Province of Jutland, in the Kingdom of Denmark, engineer, have invented certain new'and useful Improvechine with several cylinders in vertical section, and, Fig. 4; a horizontal section on line A-A in Fig. 3.

t heavy vertical shaft 1 is provided and mounted at its lower end in a step bearing 2 in a fixed arm 3 and at its-upper end in a part 4, also fixed. The shaft 1 is divided at 5 into two parts, each of which carries a crank arm 6. Through these crank arms there passes a polygonal bolt 7 which in combination with a nut 8 holds the two pieces of'the shaft 1 together. The bolt 7 is provided between the crank arms with a sleeve 9, around which one end of a piston rod 10 takes. The sleeve 9 can, when worn, be renewed. The piston rod 10 is connected at the other end with a bolt of a piston 12. The latter consists of :1, turned cylinder which has an inside bore allowing of the movement of the piston rod. The-end of the piston ismarked 13. Externally the piston carries say three piston rings 14, which a form the packing between the piston 12 and a piston chamber or cylinder 15, in which the piston reciprocates. The piston chamber or cylinder 15 is, at a suitable distance, surrounded by a jacket 16 so that between the latter and the 1piston chamber 15 a space is formed for coo ng water. The piston chamber 15 and the jacket 16 are fastened by flanges 18 and bolts 19 to a crank-case 17, which incloses the parts that take part in the movement oi the crank and is fixedly secured to the frame 3. The crank case can be divided into two or more able way.

The piston chamber 15 is connected up hy a channel 20 with special chamber '21,

pieces in a suitin which an ignition device 22 and a valve 23, i. c. the admission valve with spring, are fitted. The valve connects the chamber 21 with a carbureter, which is mounted on the frame 3 together with. the pump and the electric ignltion device. These parts are, however, not shown on the drawing as they may be of a generally known kind.

On the side away from the shaft 1 the piston chamber 15 is shaped as a cylindrical surface having the same axis as the piston 12. A steel ring 24. is fitted in a groove provided in the edge of the piston chamber and is under the action, say, of springs shaft 1 by means of a number of arms 25.

The armsare connected above with the shaft and below with the topmost annular plate 26 of the turbine, which plate is connected by a' vertical cylindrical annular plate 27 with the lowermost horizontal plate 28, of the same shape as plate 26. The annular plate 27 is provided with a bore, not shown, for'the turbine channel. On Fig. 2 a turbine channel 29 provided between the plates 26 and 28 is shown, and its shape is evident from this figure. The turbine itself is controlled by three rollers 30 rotatably mounted in a frame; the bearings for these rollers may be provided with balls. The rotation of the turbine, itself in a plane at right angles to'shaft 1 can be brought about, for example, by a guide pin or roller fitted to the frame or the front face of the piston chamber. At the upper end of shaft 1 the transmission wheel is fitted directly beneath part a.

The engine can work, say, with petrol,

which is converted into gas in a carbureter and conveyed to the motor. through the valve 28. Ignition is produced by an inductor actuated from the main shaft, which at the same time drives the cooling water pump. It may be necessary to cool not only the motor, but also the turbine channel 29, which can be done in any known way.

Tn the'piston chamber 15 the charge of vaporized petrol and air is compressed to about five atmospheres pressure, whereupon the mixture is made to explode, and the combustion gases flow out at the right moment into the turbine channel 29, which channel owing to its shape converts the force into tangential force, which, together with the reaction produced by 1 the explosive substances on leaving the mouth of the channel, and in conjunction also with the piston ressure, it' any,'f orm the forces for proucing the rotation of the machine. Packing is provided b means ofrings' 24 or in some other suitab e way. The'explosive effectcan either be imparted immediately to the turbine channel 29 or can act, shortly before discharge, on'the piston. In Figs. 3 and 4: an engine is several cylinders, four in each plane, a, b, c

and d being the four cylinders or piston.

chambers in the one plane. The four corresponding 1piston rodsare attached to a common cran pin e on the shaft 1. Only one turbine channel 29 is provided for each set of four piston chambers lying in the same plane, said channel receiving four discharges upon each complete revolution. At the moment when of the piston chamber 11. e. in. the position shown in Fig. 4, a discharge through the channel will just have taken lace. In the same piston chamber the suction will com mence immediately after the channel has passed. The suction continues until the channel is in front of the piston chamber 0. and the mixture in the first-mentioned piston chamber a is consequently compressed, while the channel passes from the piston chamber a over 11 to a. Immediately before the channel passes a the com ressed mixture is ignited, whereupon t e discharge through the channel takes place. The other pistons b, c and (i work in exactl the same manner, with the result that t e turbine channel receives a discharge for each 90 it is turned'and four fora complete revolution. The valves may be suitably operated from a common eccentric. Above these four piston chambers another set of, for

instance, 4 piston chambers in the same plane is arranged and act upon the same shaft. Fig. 3 shows two of these chambers, f and chambers of which two, h and c, are shown can be laced etc. The engine works on a two stro e cycle an explosion occurring upon each revolution. The channel 29 can, however, be made so narrow, that when passing a pistonwhamber itcannot-take the whole discharge.

Having now particularly described and ascertained the nature of my said invention and 1n what manner the same is to be per- 1 formed, I declare that. what I claim is 1. An explosion turbine comprising a rotatlng part, a statlonary inner part surrounded "by said rotating part shown with the channel 29 is in front Above this set a further set of piston and containing piston chambers open at their ends, an axial shaft for said rotating part, pistons for said piston chambers and actuated from said shaft, the said rotating-part forming the end wall of the piston chambers and having one exhaust turbine channel 29 for the piston chambers lying in the same horizontal plane, and a suitable packin interposed between the rotating part and t e piston chambers.

2. An explosion turbine comprising a rotating part having an axial shaft, a stationary inner part surrounded by said rotating part, piston'chambers contained in said stationary part and having open ends, pistons in-the said iston'chambers and actuated from the strait of the rotating part, the said rotating part having a single exhaust channel for the piston chambers lying in the same horizontal lane, the said rotating part forming the em? wall of the piston chambers and closing the same, and suitable packing interposed between the rotating part and the ends of the piston chambers.

3. An explosion turbine comprising arotating part, mounted to plane, a vertical shaft for the same, a stationary part surrounded by the rotating part, piston chambers in said stationary part, arranged in a horizontal plane, the said pistonchambers having open ends, pistons in said chambers and having piston rods, the shaft of the rotating part having a common crank pin for said piston rods, the outer open end of the piston chambers being closed by the rotating part, and means for admitting an explosive mixture to the piston chambers, the said rotating part having one exhaust channel for the piston chambers lying in the same horizontal plane.

4. In an explosion turbine, a stationary part containing a horizontally arranged piston chamber, having its outer end open throughout the area of the bore of the cylinder and curved on the arc of a circle, an

annular member rotatin in a horizontal plane and surrounding-t e stationary part he said rotating member being adapted to close the open end of the piston chamber, and

forming the outer end wall of said chamber,

the said rotating member having a single exhaust channel adapted to communicate wit-h said open end of the piston chamber, a vertical shaft for said rotating member, and a piston in said piston chamber and actuated from the shaft ofthe rotating member.

In testimony, that Iclaim the foregoing as my invention I have signed my name in .presence of two SllbSOllblIlg WltIlQSSGS.
